To all 'whom 'it may concern:

Beit known that I, GEORGE H. WAns-4 WORTH, a citizen of the United States, residing at Cuyahoga Falls, in the county of Summit and State of Ohio, have invented a cer# tain new and useful Improvement in Corc- Ovens, .of which the following is afull, clear, and exact description, reference being had to the accompanying drawings.

The object of thisinvention is to provide asimple and efficient receptacle" or cabinet The cabinet has a series of drawers or slidable shelves upon which the articles are supported and is arranged so as to facilitate access to the in' permit' the easy terior 'of the'drawers and to manipulation thereof, even though the articles contained may be of considerable. weight. The drawers carry rollers at their rear ends which ride upon stationary tubes and, telescoping with these tubes, are rods supporting the front end of the drawers. It is intended to use this cabinet in connection with a'heating devicey to form an oven in which cores may be dried. The drawers are so constructed that when pulled out, the rear end of the drawer -closes the opening and In the drawings, Figure 1 is a vertical section of my oven. Fig. 2 is a perspective thereof. Fig. 3 is a horizontal section just Fig. l4 is a detail in vertical section parallel with Fig. 1, showing the telesco infr tubes.

lIn t e drawings, my cabinet is shown as having a sheet metal casing. The sides of this casing are designated 10,. its double partiall front portion 13. fIn this front portion is set the front plate 14 of the re box, while above this fire ox is the front plate 16, which carries the front ends of the 'drawers 17 The' plate 16 is preferably of cast iron andl covers substantially the entire front of the`oven down to a oint slightly above the fire box. Be ow the front plate 16 and above the fire boxI late 14 isa suitable air damper 18. llrox rests on the casing bottom 29, andiscprovided with a top plate 20, sides 22, an un er plate 21, providing` a flue, a back plate 2,7, and a grate 23. here is an entrance door 24, lan ash doorV 2.5, a'nd a cleaning Extend-ingfromTthe upper end 1.9 of the pipe 3() into the smoke ipe:

is' a 'pipe 3 0 communicating lwith the smoke pipe 26 and provided with adamper 31. The cores being carried in the space above the fire box, it will be understood that the ,heat rising from the ire` box will dry these cores and the moisture will pass up the casing 18,and 31 regulate this amount of drying to be trolled The front plate 16`is provided with a seraft and enable the conveniently con- .ries of openings through which the drawers 17 pass. Extending fiom front to back of the furnace beneath these openings are thetubes 3``, there being two tubes for each opening. These tubes are referably screwthreaded at-their front en s into the front plate 16 (which has a reinforcing boss 36 at this point) and at their rear ends the tubes pass through the two plates 11 and 12 ofthe oven back, being locked in -place by the two nuts 37 and 38 screwin onto the tube and bearing against these p ates. At the front end a suitable nut 39 screws onto the tube The dampers i and bearin against the boss 36 securely.v

locks the tu eat this point. These pairs of tubes for each opening are thus stationary and form rigid braces for the oven from front to back.

The drawers are provided with a suitable 'bottom 40, slatted sides 41, and a rear end plate 42. Secured to this rear end are a air of brackets 43, journaled in which are ro ers 44 which ride on the tubes 35. Extendin crosswise of the drawer at its front end an( secured to it is a strengthening casting 45 which has depending ears 46, to which are secured rods 47 telescoping in the tubes 35. These rods 47 are themselves tubular. They are screw-threaded into the ears 46 and are clamped by jam'nuts 48. When the drawer is closed, the tubular rodi47 extends entirely through the tube 3 5. When the drawer is drawn out this rod draws out with it,sup. porting the frontend of the drawer, as shown 1n the case of oneof the drawers in and 2. IWhern the drawer is entirely ydrawn out, the rearI end 42y engages with the rear face of the front plate 16 and closes the opening, thus preventing the escape of heat.

To allow the -cores to be conveniently placed, "I hinge the front yplate 5() of the drawer to the front casting 45, so that the front plate may be tipped down into horizontal position, being so su )ported by lugs 51 carried by the casting 45. RN

hen the drawer the weight is very considerable and there Having` thus casing, a drawer adapted to slide` in and out 5 The cores may be properly siaced .and

supported by suitable sheet meta members 55, bent in a sinuous or ridge form and supported on the bottom of the drawers. lf desired, a sheet 'metal plate or 'plates may surmount the cores and other cores be placed on top of the plate as illustrated in Fig. 2, where 56 represents such late, and 57 and 58 the cores below it an above it yrespectively.

When the drawer is loaded with cores,

has been difficulty heretofore in easily clos- 'in the drawer. With my device, however, this difficulty does not arise, for suitable bars may be inserted in the tubes 47 as handles, and the frontend of the drawer lifted slightly to relieve the downward pres* sure at the front end of the tubes, whereupon the drawers may be easily rolled back into their closed positions ,the most of the weight being carried by the rollers'44 and only a convenient portion of it vby the operator. wheel barrow, and it may be said that each drawer in closing thus constitutes a wheelbarrow, with the corres onding advantages.

My. oven is simple an inexpensive in construction; it is ada ted to carry a large suply of cores and a oWs them to be conveniently put in the drawers and moved into lace. When closed, the su ports for the ront end of the drawers, te escoping into the stationary tubes, leave no awkward and l unsatisfactory projections. 4The arrange- 40 heat to be controlled as desired, and when ment of the pipes and dampers enables the the cores are baked, the are removed with the same ease with whic they were put in place. l A While I have disclosed my cabinet for use as a core drier, it is quite evident that its use is far more extensive, for it may be utilized to contain articles whichare dried either.

with heated air or cold air as'may be desired, and generally speaking, may be` used to support articles for any purpose whatsoever. Q f
